Based on the incredible true story of the deadliest manhunt in history......In Canada; 31st December 1931, the lone trapper Albert Johnson lives for himself in the ice cold mountains near the Yukon river. He shot and killed a man in self-defense near his renote cabin. A few days later Sergeant Edgar Millen, under protest, brought a heavily armed posse to arrest Johnson for murder. In the seige that followed, Johnson defended himself in any way possible before escaping in to the frozen mountains. As the whole nation watched, Millen was forced to pursue Johnson by foot, dogsled and plane in a desperate struggle that took both men from the brink of survival to the edge of vengeance.
